JAWABAN BESERTA CARANYA

Dalam operasi pengurangan set, kita mengurangi elemen-elemen dari set kedua dan ketiga dari set pertama. Berikut adalah hasil dari operasi pengurangan set yang diberikan:

B – C – A = {2, 4, 6, 8, 10, 1} – {3, 5, 7, 8, 9, 10} – {1, 2, 3, 4, 5, 6}

= {2, 4, 6, 8, 10} – {3, 5, 7, 9}

= {2, 4, 6, 8, 10}

A – C – B = {1, 2, 3, 4, 5, 6} – {3, 5, 7, 8, 9, 10} – {2, 4, 6, 8, 10, 1}

= {1, 2, 4, 6}

A – B – C = {1, 2, 3, 4, 5, 6} – {2, 4, 6, 8, 10, 1} – {3, 5, 7, 8, 9, 10}

= {3, 5}

C – A – B = {3, 5, 7, 8, 9, 10} – {1, 2, 3, 4, 5, 6} – {2, 4, 6, 8, 10, 1}

= {7, 9}

C – B – A = {3, 5, 7, 8, 9, 10} – {2, 4, 6, 8, 10, 1} – {1, 2, 3, 4, 5, 6}

= {7}

B – A – C = {2, 4, 6, 8, 10, 1} – {1, 2, 3, 4, 5, 6} – {3, 5, 7, 8, 9, 10}

= {} (set kosong)
